Nilai dari ²log8-²log3+²log12-²log4

= 2 log_{8} - 2 log_{3} + 2 log_{12} - 2 log_{4} \ = 2 log_{2 {}^{3} } - 2 log_{3} + 2 log_{ {2}^{2} times 3} - 2 log_{ {2}^{2} } \ = 3 times 2 log_{2} - 2 log_{3} + 2 times 2 log_{2} + 2 log_{3} - 2 \ = 3 times 1 + 2 times 1 - 2 - 2 log_{3} + 2 log_{3} \ = 3 - 0 \ = 3
semoga membantu
